Sustainable Fishing
How is commercial fishing a threat to dolphins and birdlife?
Bycatch is when the fishing industry catches a fish or any other marine species is caught while they are targeting another type of marine species. Commercial Fishing is a commonly used skill used in fishing.
Commercial fishing often uses big Gillnets, they are the biggest threat right now to Dolphins, Whales, and birdlife. Old Gillnets used to be made out of woven rope and apparently were not a big threat to them back then because they detected that some woven ropes held air bubbles that bounced off sounds sent out by dolphins and whales to navigate and find food.
In the 1980s, the idea of using plastic Gillnets came into the talk. The plastic Gillnets were lighter but stronger and lasted longer than the woven ropes. And, they were much less expensive than the ropes. The plastic Gillnets were invisible in the water and it caused more marine life to get caught. A study by the Natural Resources Defense Council (NRDC) in 2014 notes that an estimated 650,000 marine mammals (including whales and dolphins) die in foreign fisheries every year due to being hooked or entangled in nets and other fishing gear.
This Information is so amazing, I never knew that sustainable fishing wasnt a thing, and how it is a threat to the sea life... GREAT JOB MY AMAZING FRIEND!!!
ReplyDeleteHello Kahciar, you have really outdone yourself, this blog post is amazing. You explain the problem and effects in great detail and in a way that is very easy to understand. I would've loved to see what you think we could do to solve this problem, and what we can do as a country to restrict how much we fish in new zealand.
